Encoders are electric components used to measure motion, most often used to control feedback loops where knowing the angular or linear displacement of an object quickly and accurately is important. The EN12-VS20A18 is a reliable precision encoder, and its application fields and working principle are discussed in this article.

Application Fields

The EN12-VS20A18 is most commonly used in CNC machinery, where the encoder’s feedback provides precise position information to the CNC mill, router, or lathe. This encoder has a minimum resolving power of 0.0015 degree, making it a high accuracy choice for precision industrial applications. It can be used in the aerospace, automotive, and industrial sectors, for applications such as rotary servomotors, drive systems, and robotics.

Working Principle of the EN12-VS20A18

The EN12-VS20A18 is a optical encoder which uses light and photosensors together to measure the position of a rotating shaft. A light-emitting diode emits a beam of light, which is directed at a ring of reflecting elements mounted on the rotating shaft. This beam is reflected back to one or two photosensor diodes, where it is collected and converted into electrical signals. The electrical signals are then interpreted by the internal circuitry of the encoder to determine the angular rotation of the shaft.

A primary benefit of the EN12-VS20A18 is that it is designed with two outputs which can be used to provide both direction and directionless information. Directionless data provides the count of pulses over time while direction data provides information about the direction in which the rotating shaft is turning. This allows for a higher degree of accuracy and more precise control over the movements of the CNC mill, router, or lathe.

Additional features

In addition to its two output channels, the EN12-VS20A18 encoder has several additional features that make it an ideal choice for industrial applications. It has built-in temperature compensation to protect the encoder from temperature fluctuations, and is designed with robust construction to ensure long-term durability. It also has a high efficiency, with a low harmonic distortion.

The EN12-VS20A18 also has a low electrical noise level and is fully RoHS compliant, meaning there are no hazardous materials in its construction. It has a wide range of supply voltage, from 12 VDC up to 28 VDC, which makes it suitable for a variety of equipment and environments. Finally, its small size makes it an excellent choice for where space is at a premium.

Conclusion

The EN12-VS20A18 is a high-precision optical encoder which is suitable for a variety of industrial applications, including CNC machinery, aerospace, automotive and industrial sectors. It provides precise position feedback and has a wide range of features which make it an ideal choice for a wide range of motion control applications.
